fiai fi 5 muck WM JMM AJGENT PMENTEBJUN 5197a SHEET 2 BF 3 INVENTO Raf 072 5 Kfluc/c PLASTIC HAIR WAVE DEVICE AND METHOD OF WAVING HAIR BACKGROUND This invention relates to hair curling or waving devices, and more particularly to plastic clips for curlers which are intended to be used with permanent wave solutions such as those supplied with home wave kits and the like.

In the past various types of hair curling or waving devices have been proposed and produced. Some of these devices consisted of small plastic clamps and rollers so arranged that the strands of hair had to be curled on the rollers and the latter then clamped to prevent unrolling, after which waving solutions were applied to the hair, then neutralizers, washing solutions, etc. While these prior home wave devices were usable, they had a number of disadvantages. For one thing, the proper arranging of the hair about the roller was difficult and often could not be satisfactorily accomplished by the average person, also the solution that was applied tended to evaporate or run, leaving portions of the curled hair too dry and impairing the efficiency of the curling procedure. For another thing, the applying of the waving solution tended to be messy and resulted in soaking of the scalp. It invariably required a certain amount of skill and technique, especially if a woman was working on her own hair. Additionally, in many instances the curls that were produced were too tight, resulting in a kinky look after the curlers were removed and the hair was neutralized, washed and combed out.

SUMMARY The above drawbacks and disadvantages of prior hair curling devices are obviated by the present invention, which has for one object the provision of novel and improved plastic clips for hair waving devices, which clips are especially easily utilized in the procedure for waving ones own hair in conjunction with wrappers which minimize drying out or evaporation of the waving solution. A related object of the invention is to provide improved plastic clamping-type clips for use with paper wrappers, which can be economically fabricated essentially as simple one-piece, molded plastic articles especially adapted for use in conjunction with said wrappers, thereby to reduce costs to an absolute minimum.

The foregoing objects are accomplished by a novel molded plastic dual-clip device comprising an elongate centrally-disposed body member having integral therewith a pair of resilient side clamping arms which are coextensive with the body member and connected thereto by resilient connecting webs constituting hinges in effect. An elongate paper wrapper can be at one end clamped between one side arm and the body member of the clip device; selected strands comprising a bunch of hair are then arranged to be clamped adjacent the scalp between the body member and the remaining clamping side arm. The hair is placed so as to overlie the paper wrapper, whereupon waving solution is applied; thereafter side marginal portions of the paper wrapper can be folded inward over the hair in overlapping relation. Finally, the folded wrapper is rolled or curled, starting with the free end thereof, until it is brought in close proximity to the novel plastic clip device. The inherent ductility of the folded wrapper with foil facing is such that the roller wrapper retains its shape without any additional fastening means being required on the clip. The curling or waving solution, being contained in the folds of the rolled wrapper, is prevented from evaporating and instead the hair remains moist and the solution active. After an interval of time, the wrapper is unrolled and opened, and the novel clip device released whereupon it can be readily removed from the hair that has been treated. The entire waving device is thus seen to consist essentially of only two parts, the molded plastic clip part as provided by the invention and the foil-backed paper wrapper part.

Other advantages of the invention reside in the provision of an improved hair curler or waving device as above characterized, which is especially easy to operate in effecting the clamping of the paper wrapper and also of the strands of hair, and in arranging the hair over the wrapper, folding the wrapper inward in overlapping relation and thereafter rolling or curling the wrapper to its final position.

Still other features and advantages will hereinafter appear.

FIG. 18 is the front elevational view of a molded onepiece plastic clip device constituting yet another embodiment of the invention, and

FIG. 19 is a side elevational view of the clip device of FIG. 18.

Considering first FIGS. l-11, the plastic clip of the permanent waving device as provided by the invention is shown as comprising essentially a one-piece molded plastic piece designated generally by the numeral 20, which is especially adapted to be used with a paper or paper-like foil-backed wrapper member designated 22. The plastic clip 20 comprises a centrally-disposed elongate body member 24 of generally rectangular cross section, which is at one end joined by two curved, resilient connecting webs 26 respectively to a pair of side clamping arms 28. The side clamping arms 28 are slightly curved, and have a T-shaped cross section comprising a flat main portion 30 and a centered strengthening rib portion 32'.

At its free end the body member 24 has a' retainer socket in the form of an arcuate or curved portion 34 presenting a concave end face 36 which is adapted to accommodate bulbous or bill portions 38 of partially circular or semi-circular hook formations 40 provided on the free extremities of the side arms 28. The hook formations 40 are curved and resilient, and enable the bulbous portions 38 to be forced up and over side edges 42 of the socket portions 34. The four corners of the socket portion 34 have small upstanding nibs 44 which constitute guides and retainer devices to guide the hook portions 38, 40 of the side arms as the latter are being forced and clamped onto the arcuate portion 34 of the body member 24. FIG. 3 shows one side arm in its clamped position, with the remaining side arm still unclamped.

The center, body member 24 can also be provided with a rubber or other non-slip sleeve or jacket 46 for cooperation with the clamping arms 28 to provide a non-slip grip when the arms are closed or in clamping position. The jacket 46 has a cross-section substantially in the shape of the letter C.

Referring to FIG. 5, the wrapper 22 can comprise a sheet of paper having a foil backing. The configuration of the wrapper 22 is generally rectangular, each wrapper having a grip tab 48 and side flaps 50 which are joined to the center or main body portion 52 along fold lines 54.

Referring to FIG. 6, the grip tab 48 of the wrapper 22 is shown as being clamped between the body 24 of the plastic clip and one of the side arms 28 thereof. Also in FIG. 6 are illustrated strands of hair 56 which are clamped to and frictionaily seized by the plastic clip by the other one of the side arms 28 thereof. The hair strands 56 are shown as overlying the central or body portion 52 of the wrapper 22.

The application of the waving device to the head of a user in the manner shown in FIG. 6 is also depicted in FIG. 1 wherein the plastic clip 20 has a wrapper 22 attached to it and also is clamping the strands of hair 56 which are to be curled or waved. After application of the waving solution to the hair 56 which overlies the wrapper 22 has been effected, the side flaps 50 of the wrapper are folded inward over the hair and in overlapping relation. This is illustrated in FIGS. 1 and 7. Thereafter, the folded wrapper is curled or rolled upward as indicated in FIGS. 1, 7 and 8, the rolling being completed when the plastic clip 20 is reached as shown by the fully applied waving device designated at 58 in FIG. 1.

The use of a foil backing on the paper of the wrapper 22 has several advantages. It prevents the waving solution from leaking or dripping out of the rolled up wrapper, and prevents drying out of the solution. Also, the foil imparts ductility or a body to the wrapper, and enables it to retain various given shapes. Thus, when the wrapper is rolled up as indicated at 58 in FIG. 1, it will retain the rolled-up shape without any additional holding devices required of the clip 20.

After a predetermined period of treatment of the hair with the waving solution, the waving device is removed from the head by merely unrolling the wrapper 22 and loosening the clamping side arms 28 of the plastic clip. Such loosening may be easily effected by applying a twisting force to the hook portions 38 of the arms 28 in a counterclockwise direction as viewed from the end of the plastic clip. This is illustrated in FIG. 7 by the arrows. Such counterclockwise or unscrewing movement is similar to that which is naturally employed when unscrewing a nut, for example, from a screw and is the natural movement that most people are familiar with. The application of such force to remove the clip will cause the portions 38 of the arms 28 to be forced over the small detent nibs 44, since these are of relatively low height and are not intended to provide a permanent restraint of the clamping arms.

As shown in FIGS. 10 and 11, the portions 38 of the clamping arms are of tapered configuration in addition to being oval whereby they can nest one against the other as seen in FIG. 11 so that each occupies a comparable portion of the top area of the arcuate part 34 of the clip.

Another embodiment of the clip part of the invention is illustrated in FIGS. 12 and 13. In this embodiment there is shown a one-piece molded plastic clip having a central, straight body portion 62 which at one end is connected to curved, side clamping arms 64 and 66 by resilient curved webs 68. The free end of the center body member 62 has a rounded enlargement or head 70 adapted to be received in a semi-circular hookshaped bent portion 72 of the am 66, having a bill 73. Due to the resilience of the arm 66 and of the plastic material making up the clip, the hook portion 72 can be readily snapped over the head 70. The free extremity of the arm 64 has a larger semi-circular hook portion 74 with a bill 75 which is adapted to be snapped over the hook portion 72 of the arm 66 after the latter has been clamped against the center body member 62. A small undercut or shoulder 76 on the hook 72 can engage an internal shoulder or undercut 78 of the hook 74 to effect a more secure retention of the clamping arms, as will be understood. The body member 62 can have a plurality of transverse ribs 80, and the arms 64, 66 can have cooperable ribs 82 to provide a non-slip arrangement which minimizes the likelihood of the wrapper 22 pulling away from the clip, or of the clip being loose on the strands of hair which are being clamped.

Still another embodiment of the invention is illustRated in FIGS. 14 and 15. The one-piece plastic clip illustrated therein comprises a center body member 86 at one end joined to two curved resilient side clamping arms 88. The body member 86 has at its free end a hooked member or head portion 90 provided with a pair of spaced depending retainer tabs 92. The free ends of the side clamping arms 88 have retainer nibs 94 adapted to be slipped under the tabs 92 to hold the arms clamped against the body member. In effecting such clamping, the resilient arms 88 are forced slightly sidewise or edgewise to bring the tabs 94 thereof in the retained positions between the tabs 92 and the body member 86.

Yet another embodiment of the invention is illustrated in FIGS. 16 and 17, wherein there is shown a one-piece molded plastic clip comprising a central body member 98 having a folded-back or hook-like head portion 100 spaced therefrom at its free end, the other end of the body member being integrally secured to curved resilient side clamping arms 102 and 104. The free extremity of the arm 102 has a tab 103 which is adapted to he slid under the bill portion 106 of the hook 100, and the free extremity of the arm 104 has a hook configuration 108 adapted to be hooked over the head 100 of the body member 98. A retainer shoulder 110 on the head 100 is cooperable with a shoulder 112 of the hook formation 108 to effect a more secure retention.

Still another embodiment of the invention is illustrated in FIGS. 18 and 19, which show a one-piece molded plastic clip comprising an elongate central body member 114 having at its opposite ends curved resilient webs 116 on which are carried side clamping arms 118 provided at their free extremities with resilient semi-circular hook formations 120 including bulbous bill portions 122. At the ends of the body member 114 retainer hooks in the form of curved tabs 124 are provided, to be received in the hook formations 120 so as to retain the arms clamped against the body member. In effecting such clamping, the hooks 120 will yield, and the bulbous bill portions 122 will be forced over the curved tabs 124, as can be readily understood.

It will now be seen from the foregoing that I have provided a novel and improved one-piece plastic clip for use in a hair-waving device, said clip comprising an extremely simple, low-cost one-piece molded plastic piece especially adapted for use with a foldable paper wraPper so as to be cooperable in a manner to enable a user to easily and quickly roll up strands of hair which have been treated with a waving or curling solution. The clip device can be easily and quickly operated when being applied to the head by the user in the desired manner, and the hair strands will be properly confined and kept moist while being subjected to the action of the waving solution. Relatively little skill is required in utilizing the device, and the clamping and unclamping action may be easily and quickly effected. By the use of the foil-backed paper wrapper in conjunction with the plastic clip there is minimized messiness and loss of solution or waving fluid during the hair curling treatment.

Variations and modifications are possible without departing from the spirit of the invention.
